2.B: Growth, reproduction and dynamic homeostasis require that cells create and maintain internal environments that are different from their external environments.
2.B.1: Cell membranes are selectively permeable due to their structure.
2.B.2: Growth and dynamic homeostasis are maintained by the constant movement of molecules across membranes.
LO 2.7 Students will be able to explain how cell size and shape affect the overall rate of nutrient intake and the rate of waste elimination. [See SP 6.2]
LO 2.6 The student is able to use calculated surface area-to-volume ratios to predict which cell(s) might eliminate wastes or procure nutrients faster by diffusion. [See SP 2.2]

Group 1
Draw a prokaryotic cell, be sure to include and label all structures (internal and external) and be ready to explain the functions of those structures. What similarities and differences do prokaryotic cells share with eukaryotic cells? From an ecological, medical and economic basis why are prokaryotes important- be ready to provide specific examples.
Group 2
Draw a eukaryotic plant cell, be sure to include and label all structures and be ready to explain the functions of those structures. What similarities and differences do eukaryotic cells share with prokaryotic cells? What structures do plants share with animal cells. What differences exist between these two cell types? What is thought to be the evolutionary history of the animal cell’s chloroplasts?
Group 3
Draw a eukaryotic animal cell, be sure to include and label all structures and be ready to explain the functions of those structures. What similarities and differences do eukaryotic cells share with prokaryotic cells? What differences exist between these two cell types? What is thought to be the evolutionary history of the animal cell’s mitochondria? How is active transport different than passive transport. How do water molecules get through the cell membrane?
Group 4
Make a drawing that illustrates the fluid-mosaic model of the cell membrane. Be sure to label all parts and be ready to explain their functions. Be able to explain the following cellular processes: diffusion and osmosis. Use the following terms to explain how water moves between a cell and its environment: hypotonic, isotonic and hypertonic. How is active transport different than passive transport. How do water molecules get through the cell membrane?
